Polyurethane is a polymer material with properties such as high elasticity, wear resistance, tear resistance, and impact resistance. PU injection wheels are typically made from polyurethane casting elastomer raw materials. Depending on the raw materials used, they vary in terms of yellowing resistance, wear resistance, transparency, and hardness. There are many types of tooling for injection wheel production, with injection wheel production molds being a common example.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0028] Please see Figure 1-5This utility model provides an embodiment of a casting wheel production fixture, including a chassis 1. Multiple mounting grooves 15 are provided on the outer side of the chassis 1, and these grooves are evenly distributed in a ring about the vertical center line of the chassis 1. A soft rubber pad 16 is fixedly connected to the bottom of the chassis 1, with the top surface of the soft rubber pad 16 adhering to the bottom surface of the chassis 1. The chassis 1 allows the device to be placed on an external horizontal surface. The soft rubber pad 16 ensures a tight fit between the bottom of the device and the external horizontal surface. The mounting grooves 15 and external bolts are used in conjunction to fix the chassis 1 to the external horizontal surface, thus completing the installation of the device.

[0029] In this embodiment, a blanking groove 2 is fixedly connected to the top center of the chassis 1, and a central column 3 is rotatably connected to the center of the blanking groove 2. The central axis of the central column 3 coincides with the vertical center line of the blanking groove 2. Multiple telescopic rods 4 are fixedly connected to the top outer side of the chassis 1, and the top of the multiple telescopic rods 4 is fixedly connected to the same top frame 5. A molten material inlet 6 is rotatably connected to the center of the top frame 5. The outer dimensions of the molten material inlet 6 match the inner dimensions of the blanking groove 2, and the vertical center line of the molten material inlet 2 coincides with the vertical center line of the blanking groove 2. The vertical center lines of 2 coincide, and a slot 12 is provided at the center of the bottom surface of the injection groove 6. The inner diameter of the slot 12 matches the outer diameter of the center column 3. The telescopic rod 4 allows the top frame 5 to move down, making it easier to cover the injection groove 6 on the blank groove 2. The setting of the center column 3 and the slot 12 makes the injection groove 6 more stable when it covers the blank groove 2. The rotatable connection between the center column 3 and the blank groove 2 makes it easy to rotate the center column 3 to demold the injection wheel after it is formed.

[0030] In this embodiment, the bottom of the injection trough 6 is provided with multiple material conveying holes 7, and the multiple material conveying holes 7 are evenly distributed in a ring about the vertical center line of the injection trough 6. Through the multiple evenly distributed material conveying holes 7 on the injection trough 6, the billet can be evenly input into the billet trough 2, ensuring the uniformity of material conveying and preventing accumulation during material conveying. A gear ring 9 is fixedly connected to the top of the injection trough 6, and a motor 10 is fixedly connected to one side of the top frame 5. A gear 11 is fixedly connected to the output end of the motor 10. The gear 11 and the gear ring 9 are meshed. When the motor 10 is started, the gear 11 can rotate, driving the gear ring 9 and the injection trough 6 to rotate, which facilitates the conveying of the billet to different positions in the billet trough 2, further improving the uniformity of material injection and ensuring the quality of the injection wheel molding.

[0031] In this embodiment, the inner wall of the top frame 5 is provided with an annular groove 8, and the annular groove 8 is connected to the injection groove 6 by a slider. The inner side of the annular groove 8 fits against the outer side of the injection groove 6. The arrangement of the annular groove 8 and the slider can ensure the stability of the rotation of the injection groove 6.

[0032] In this embodiment, a knob 13 is rotatably connected to the center of the injection tank 6, and a sealing frame 14 is fixedly connected to the outside of the knob 13. Rotating the sealing frame 14 can block the material feeding hole 7. After the injection is completed, rotating the knob 13 can drive the sealing frame 14 to rotate, so that the material feeding hole 7 can be blocked by the sealing frame 14, thereby stopping the material feeding.

[0033] In this embodiment, the inner wall of the billet groove 2 is provided with a cavity, and a sealing plug 17 is threadedly connected to the front side of the billet groove 2. By rotating the sealing plug 17 and removing it, the cavity of the billet groove 2 can be opened. By rotating the sealing plug 17, the cavity in the inner wall of the billet groove 2 can be opened, and coolant can be injected into the cavity to cool the billet in the billet groove 2, accelerate the billet forming speed, and improve the production efficiency of the injection wheel.

[0034] Working principle: When using this device, the base plate 1 first allows the device to be placed on the external horizontal surface. The soft rubber pad 16 ensures a tight fit between the bottom of the device and the external horizontal surface. The mounting groove 15 and the external bolts are used to fix the base plate 1 to the external horizontal surface, completing the installation of the device. The telescopic rod 4 allows the top frame 5 to be lowered, making it easier to cover the blank groove 6 with the injection groove 2. The central column 3 and the bayonet 12 make the injection groove 6 more stable when it covers the blank groove 2. The rotatable connection between the central column 3 and the blank groove 2 makes it easy to rotate the central column 3 to demold the injection wheel after it is formed.

[0035] Through multiple evenly distributed feeding holes 7 on the injection trough 6, the billet can be evenly fed into the billet trough 2, ensuring the uniformity of feeding and preventing accumulation during feeding. At the same time, starting the motor 10 can make the gear 11 rotate, driving the gear ring 9 and the injection trough 6 to rotate, which facilitates the feeding of the billet to different positions in the billet trough 2, further improving the uniformity of feeding and ensuring the quality of the injection wheel molding. The setting of the ring groove 8 and the slider can ensure the stability of the rotation of the injection trough 6.

[0036] After the material is injected, the sealing frame 14 can be rotated by turning the knob 13, which can block the material feeding hole 7 and stop the material feeding. Rotating the sealing plug 17 can open the cavity in the inner wall of the billet groove 2 and inject coolant into the cavity to cool the billet in the billet groove 2, speed up the billet forming speed and improve the production efficiency of the injection wheel.
